J'AMESH. COOK, or TULSA, OKLAHOMA ANcnon STAPLE FOR MULCHING PAJEER,

Application filed .Tune 17,

My invention relates to anchoring staples and more particularly to a device of that character for anchoring mulching papento Y the ground; the principal object of the 1n.-

paper sheets secured tothe ground by staples of my improved construction.

Fig. 2 is a perspective view of one of the staples showing its assembled relation with the mulching paper and its anchorage 111 the ground. a V Fig. 3 is a detail perspective vlew of'the 29 staple.

Referring in detail to the drawings: 1 designates mulching paper sheets arranged to cover thesurface of the ground around growing plants and herein shown 4 having overlapped edges 2 bound together and secured to the ground by the staple 3.

Each staple 3-comprises a single piece ,of wire 4: having convolutions .5 throughout its length and bent, to provide spaced anchor legs 6 at opposite ends and alt-right angles to a central body portion? adapted to lie flat on the mulching sheets when the legs6 are projected through the sheets and into the ground. I In I manufacturing the staples, straight wire of desired thickness or gauge is passed through a forming machine whereby convolutions 0r corrugations of desired spacing 0 and width are formed, after which the corrugated wire iscut up into strips of desired length, and the end. portions of the strips may be pointed and bent at right angles to form the anchor legs.

In using the staples the anchor legs are inserted through the mulching sheetsand into the ground the convolutions serving to secure the legs in the ground and to cover a comparatively large surface on the sheets for V reinforcing the paper, thereby preventing 1929. Serial No. 371,445.

displacement and damaging of the paper by wind.

' \Vhile the staple is shown applied through the overlapped edges of mulching sheets, it IS obvious that the staples will be equally 5. sufiicient for securing separated sheets to the ground.

What I claim and desire to secure by Letters Patent is:

A staple of the character described comprising a single piece of corrugated wire havlng a flat body portion and leg portions extending at right angles to the body portion.

A staple of the character described c0m- Y prising a single piece of wire having corrugations throughout its length and bent to provide a flat body portion, and leg portions extending at right angles from opposite ends of the body portion.

3. A staple of the character described comprising a single piece of corrugated wire having a body portion constituting a level reinforcement strip, and end portions at right angles to the. body portion and constituting anchor legs.

A staple of the character described comprising a single piece of corrugated wire having a level body portion and angularly disposed anchor legs,

5..A staple of the character described comprising a single piece of wire including a level-body portion bent to form relatively large corrugations, and angularly disposed anchor legs bent to form smaller corrugations.

6. A staple of the character described com- A prising a single piece of wire including a level body portion bent to form relatively large corrugations, and leg portions bent into smaller corrugations extending at right 90 angles from opposite ends of the body portion;

7 A staple of the character described come prising a single piece of wire including, a level body portion bent to form relatively 95 wide and shortcorrugations, and angularly. disposed legs bent to form relatively narrow and long corrugations.

In testimony whereof I affix my signature.
